Last week, the Centers for Disease Control and Prevention (CDC) released a new report on obesity and found that there was a 1.1 percent increase (an additional 2.4 million people) in the self-reported prevalence of obesity between 2007 and 2009, plus the number of states with an obesity rate over 30 percent has tripled to nine states. In 2000, there were no states that had an obesity rate of 30 percent or more. The rise in obesity in the United States has become a huge public health and medical cost concern, but there are other impacts. Obesity has caused more people to buy larger vehicles, which increases gasoline consumption in the U.S. and fuel consumption increases with more weight in cars either from people or cargo.
A detailed study published in 2006 at Entrepreneur.com analyzed the amount of additional fuel consumed due to heavier drivers. One key finding was that almost 1 billion gallons of gasoline per year can be attributed to passenger weight gain in non-commercial vehicles between 1960 and 2002--this translates to .7 percent of the total fuel used by passenger vehicles annually.
